They ran nonstop for three days,
and still work perfectly. I might also
add that it ran three days on the same
set of batteries.

I also had a chance to use the
Tactic TTX600. This is the six-channel
version of the radio, and would be
recommended if you want a low radio
with a little expansion capability.

The only downside to these radios
is that the throttle has detents — not
good for helis or quads where precise
throttle control is needed. I did open
up my radio and file down the
detents, so it works a lot better.

Futaba 8FG Super

I can't say enough about this
radio. It's a standard eight-channel
radio, however, if you use the S-bus
function you get 12 proportional
channels and two switched. Every
single knob, switch, or trim is
assignable.

There are eight switches — six of
which are three-position switches.
There are two knobs on the front and
two sliders on the back. You have
your two main joysticks that control
four axes. There are four digital trims
that can be assigned as you see fit.

The radio will store 20 models
and has a slot for an SD card so that
you can store more.

All of these features are nice, but
the main reason I purchased the 8FG
was that many of the new flight
controllers coming out support the
S-bus.

This means just a single wire from
the receiver to the flight controller,
not eight. (More on this when I talk
about the flight controllers in the next
section.)

Radio Cross-Compatibility

There is no cross-compatibility.
A receiver designed for the Tactic will
not work on the Futaba. They all have
their own proprietary systems for
managing the 2. 4 GHz frequency
spectrum.

There is one exception to this.
Since the Futaba receivers are so
expensive ($140 or more), many of
the other manufacturers are making
